Description

Compared with other compounds in its class, the molecular weight of 140.14 g/mol gives 5,7-Diazaspiro[3.4]octane-6,8-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5,7-Diazaspiro[3.4]octane-6,8-dione (CAS 89691-88-3), molecular formula C6H8N2O2 and molecular weight 140.14 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5,7-Diazaspiro[3.4]octane-6,8-dione (C6H8N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 140.14 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
